What numbers would you subtract from each side of the equation x + 12 = 17 + 3 to get the variable by itself ?

The number you would subtract on both sides would be 12... but this in and of itself is not the first step. the way you would solve this is by:
combine like terms. x + 12=20
then, subtract 12 from both sides to get variable alone.
you will end up with a final answer of x=8

Answer from: realneggalloyd

Ok so basically when you work with equations you want to do the opposite regardless if the sign is adding or subtracting do the opposite. Ok so x+12=17+3 So first we can not simplify the numbers on the left side so we leave it. Now 17+3 is 20 so x+12=20 do the inverse because you want to get x by itself to see what its secret number is. so 20-12 is 8 x=8 hoped that helped .:))

step-by-step explanation:

hello and welcome!

so, when we see the words "proportional" along with a table, we need to know that we're looking numbers that divide by the same thing.

looking at this table, we simply have to do a trial and error, and divide to see which numbers have the same quotient. if you look at choice a & c, they both have equal quotients for three of the numbers, with one exception, so those can't be the answer. looking at b, there is no similarity, so that can't be it. then, we see d; if you divide all the numbers in the table, you'll see that they all divide by two, which is a proportional relationship, and our answer!

$4/2 = 2\\7/3.5=2\\8/4=2\\10/5=2$

also, always remember that the x will always be the number that goes into y, and somewhere behind this table, is a formula. for this specific table, the formula would be:

$y=\frac{x}{2}$

since our x-value is being divided by two to get the y-value. and if they were to ask for more numbers in the series, this is the formula you would use to find them.
